when turned on and beep once when turned off.
Hold Key
Pressing this key will lock the current angle reading
displayed on the LCD.
Sound/LCD Backlight Key
Press this key once and hold for 2 seconds to turn on/off
the LCD back light. The instrument will beep once. Press
button once to turn on/off the sound function. When sound
function is on you will see the horn symbol on the LCD. There will

will start as you move closer to level or plumb. A steady tone will
beep when level is at 0.0º or 90º.
Push the MODE button to switch from one construction language
to another. This controls which construction language your
electronic module will measure in. Your level has the capability to
measure in Degrees, Percentage of slope, Millimeters per Meter, Inches
per Foot (Slope, Pitch) in decimal form and Inches per Foot in fractions of
an inch. A symbol on the upper right of the screen will explain which
MODE you are currently in.
Laser Key
Turn on/off the laser. The instrument will beep once.
Calibration Key
Please refer to Section 8 “Self-Check and Fine Calibration”.

The triangle arrows displayed on the two ends of the LCD indicate
the inclination direction of the laser digital level.
1. Press and hold the ZERO key for 3-plus seconds, unit will beep once.
When the LCD shows -0-, it means the instrument has already
entered the calibration status.
2. Place the laser digital level on the horizontal reference surface, as
shown in figure 5, after 10 seconds, press the ZERO again, and the
LCD shows -1-.
3. Turn the laser digital level 180 degrees, as shown in figure 6, and
after 10 seconds, press the ZERO key again, and the LCD shows -2-.
Wait for 2 seconds, and the laser digital level will show the angle
reading. The horizontal calibration is now completed.
Vertical Calibration
1. Press and hold the ZERO key for 3-plus seconds,
unit will beep once. When the LCD shows -0-, it
means the instrument has already entered the calibration status.
2. Place the laser digital level on the vertical reference
surface, as shown in figure 7, after 10 seconds,
press the ZERO again, and the LCD shows -1-.
3. Turn the laser digital level 180 degrees, as shown in
figure 8, and after 10 seconds, press the ZERO key
